said co-author Professor Eric Steig from the University of Washington in Seattle.<\/p>\n<p>&#8220;It depends on how climate changes over the next few decades, which we could influence in a positive way by reducing greenhouse gas emissions.&#8221;<\/p>\n<p>The researchers observed that while in one region, in the Bellingshausen Sea, the pace of ice retreat accelerated after 2003, it slowed in the Amundsen Sea.\n<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%E2%80%98Blink_of_an_eye\"><\/span>&#8216;Blink of an eye&#8217;<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>They concluded that this was down to changes in the strength and direction of offshore surface winds, which can change the ocean currents and disturb the layer of cold water around Antarctica and flush relatively warmer water towards the ice.<\/p>\n<p>Both the North and South pole regions have warmed by roughly three degrees Celsius compared to late 19th-century levels, nearly three times the global average.<\/p>\n<p>Scientists are increasingly concerned that the Pine Island and Thwaites glaciers have reached a &#8220;tipping point&#8221; that could see irreversible melting irrespective of cuts to greenhouse gas emissions.<\/p>\n<p>Anders Levermann, a climate scientist at the Potsdam Institute for Climate Impact Research who was not connected to the latest study, welcomed the <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp;
